Abstract
The invention relates to preparation of silicon rubber materials, in particular to an insulator silicon rubber used in an insulator of electric equipment and a method for preparing the same. The insulator silicon rubber comprises the following raw materials in portion by weight: 10 to 25 portions of crude rubber of which the molar content of vinyl groups is 1 percent, 60 to 100 portions of crude rubber of which the molar content of vinyl groups is 0.14 percent, 40 to 60 portions of pyrogenic silica, 5 to 10 portions of dimethyl dimethoxy silane, 100 to 300 portions of aluminum hydroxide, 1 to 3 portions of vinyl tri-methoxysilane, 2 to 4 portions of dimethyl-silicon oil, and 1 to 3 portions of titanate coupling agent. Actual tests show that the insulator silicon rubber possesses good insulating property and enough hardness and strength, is difficultly deformed, and can completely meet the use requirements of high-voltage electric insulators.

Manufacture method of the present invention is based on above-mentioned raw material to be formed, and its steps in sequence is:
A. be 20 parts of 1% methyl ethylene rubbers with the vinyl molar content, with the vinyl molar content be that 0.14% methyl ethylene rubber stirred 2-4 minute in kneader for 70 parts;
B. 45 parts of white carbon blacks and dimethyldimethoxysil,ne are added for 8 parts several times, fully stir each back that adds, and obtains silicon rubber gross rubber;
C. it is kneaded and formed to add 280 parts in aluminium hydroxide, 3 parts of vinyltrimethoxy silanes, 3 parts of dimethyl silicone oils, 2 parts of titanate coupling agents;
D. after kneaded and formed, be warmed up to 150 ℃, vacuumize, logical cooling water temperature to 80 ℃, plastic emitting;
F. the plastic emitting postcooling obtains product to room temperature.
Product of the present invention has the good insulation performance performance through actual detected, has enough hardness, intensity simultaneously, and is not yielding, can satisfy the service requirements of insulating of electric measurement of high pressure fully.
Embodiment
Embodiments of the invention are made insulator silicon rubber through following steps,
A. be 1% methyl ethylene rubber with the vinyl molar content, with the vinyl molar content be that 0.14% methyl ethylene rubber stirred in kneader 2-4 minute;
B. divide three addings with white carbon black and dimethyldimethoxysil,ne, stirred 20 minutes each back that adds, and obtains the silicon rubber gross rubber of mechanical property excellence;
C. add aluminium hydroxide, mediate 60min, temperature is controlled at below 130 degree;
D. after kneaded and formed, be warmed up to 150 degree, vacuumize, logical cooling water temperature to 80 degree, plastic emitting;
F, the plastic emitting postcooling obtains product to room temperature.Can add vulcanizing agent sulfuration in the use again, 170 degrees centigrade of sulfurations 5 minutes down, 200 degrees centigrade of post cures 4 hours.
Above-mentioned raw-material parts by weight are:
23 parts of the rubbers of vinyl molar content 1%
85 parts of the rubbers of vinyl molar content 0.14%
50 parts of gas-phase silicas
8 parts of dimethyldimethoxysil,ne
220 parts in aluminium hydroxide
2 parts of vinyltrimethoxy silanes
3 parts of dimethyl silicone oils
3 parts of titanate coupling agents.
To the insulator silicon rubber that the foregoing description is made, test insulating property with the 1mm test piece, performance such as following table:
